My father build a lot larger machine as his master's thesis in the early 80's. All the programming had to be done in assembly. So I don't envy him.

My goal is to make injection molded parts. Step 1 is to make a CNC machine; Step 2 is to make an injection molding machine. I need a CNC that can operate on a 12" square bed to make an 8 cavity mold. No commercial desktop CNC as far as I can see can do this (Lightmachines has a 12"x7" bed). In your opinion, can I make a durable/accurate desktop machine with 12"x12" travel that can cut tool steel (or at least aluminum)?]]>Mar 10th 2007 5:46PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/Jun 29th 2006 8:55PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/
I recommend that everybody who is seriously thinking about building one of these look on eBay for old line printers, preferably one that is not from a 'home' environment. Sure, the old ImageWriter is an easy find on eBay, but lets face it--it was never designed for 16 hours of continuous use, running over 7000 pages a day, 5 days a week.

I work in a computer warehouse, so I snagged quite a few 1.8 degree steppers and a whole heaping helping of stainless steel rod that will be perfect for the table. The best part is, these motors will half-step which will only make my CNC even more accurate.

I'm going to use mine for milling out PCB's instead of using etching fluid. Blech. Why use dirty, nasty, stinky etching fluid when you can simply slap a PCB down and have it mill out the circuit and then drill it? Just tin and you’re done.]]>Jun 29th 2006 10:19PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/Jun 29th 2006 11:40PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/Jun 30th 2006 1:27AMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/

This is an fasinating article, even if you don't want to build one, or didn't intially know what a CNC machine was. That's why we visit Engadge - to learn.

Since this is such a challenging homebuild project, there must be some really neat things this CNC can be used for. ]]>Jul 5th 2006 5:42PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.taomc.com/art_machines.htm]]>Jul 12th 2006 3:00PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/Jul 12th 2006 3:43PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/Jul 13th 2006 6:22AMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/If you're such a moron you don't know what CNC is, then;

1. Another good source for hobby CNC parts is old scanners. Many of these contain two-rail positioning systems with stepper motor/timing belt drives that can be adapted immediately to CNC router use. Older scanners moved fairly heavy lens systems about -- so their mechanics tend to be "robust."

2. The NJM3517D2 available from Mouser is an alternative unipolar stepper motor controller IC that offers full and half-step control, forward or reverse, for under $3.00.

3. Harbor Freight Tools offers a 12VDC rotary tool like a dremmel, but much lighter, for under $10. Since it's 12VDC, it's easy to control on/off.

4. Suggestion: build your first machine for fun and to get some appreciation of the
hardware and software challenges. Worry about accuracy on your second machine. Then buy your third machine from a commercial supplier if you really need that 0.001 accuracy. ]]>Jul 18th 2006 11:01PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/Jul 19th 2006 7:40PMhttp://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/
If you cannot follow the instructions in these documents to successfully make a working desktop CNC machine then I feel your situation is hopeless. I paide $35 bucks for Kleinbauer's "Brute" plans, then spent considerable time simplifying the construction with the intent of publishing an easier to manufactuer machine. Somebody else beat me to the goal, apparently in 2004. Wish I had found this before I sent off the $35!

Additionally , I lucked out in 2 ways, first I found a set of new old stock stepper motors on ebay for 16$ shipped..
second...at a garage sale I found an old exercise machine, a rowing/ski machine, which with some modifications proved to save me TONS of work and money in assembling my x axis ($5 bucks and 20 minutes well spent)
Additionally, I happen to have a dremel router attachment (not the table, the handheld model) which at the very least will prove useful for holding my dremel in place and may very well serve as a solid basis for my z axis

To PC board makers: I've been using an old HP pen plotter and TurboCad software to draw directly onto copper laminate. I have been able to do double sided PCBs on a 50mil grid reliably using "Sharpie" markers for resist pens. The whole rig, complete with plotter and software, can be had from ebay for about $60. Of course you'll need to make a little "tooling" (only tools needed: scissors!) and do some software hacks -- but you're ready for that, or you wouldn't be here! :)

Loved the rowing machine x-axis! I gave my machine to a friend a few years back.
